Definitions
- the invention relates to a filling shoe for rotary tablet presses, and, more particular, to a filling shoe including a filling shoe housing, which can be positioned above a die plate of a rotor of the rotary tablet press, with at least one discharge opening for a starting product which is to be compressed and with a seal for sealing the gap between the rotatable die plate and the filling shoe housing, which seal is fastened or can be fastened exchangeably to a bottom wall of the filling shoe housing that contains the discharge opening.
- the invention also relates to the seal for sealing the gap.
- the product which is to be compressed such as, in particular, a powder for the production of medicaments or a powder for the production of cleaning tablets or the like
- a powder for the production of medicaments or a powder for the production of cleaning tablets or the like is fed, via suitable channels or hoses, a hopper and a feed member, referred to as a filling shoe, to the dies which are interchangeably inserted in the die plate, with the fed-in powder being pressed with the holes of said dies to form a tablet of the desired shape by means of punches moved in opposite directions.
- the hopper and the channels can also form an integral component of the filling shoe.
- the filling shoe can be mounted in a fixed position relative to the die plate or else be fastened to a pivoting device which in the course of operation is pivoted into its operating position in which the filling shoe assumes a predetermined position relative to the dies in the die plate.
- Impeller wheels or other movable distribution members which are motor-driven are frequently arranged inside the filling shoe so that the product or powder which is to be compressed can be better distributed over the die holes which are to be filled by means of the filling shoe.
- the filling shoe should at the same time ensure that the product to be compressed, such as, in particular, powder, substantially only fills the die hole to the desired filling height in order to avoid product losses and to achieve a favorable metering accuracy of the product or powder to be compressed.
- a seal which is made of a material which is optimally tailored to the product to be compressed is fastened to the underside of a bottom wall of the filling shoe housing that surrounds the discharge opening.
- Customary materials for such seals can be, for example, bronze, stainless steel or plastic and, depending on the product to be compressed that is used, the intended purpose, the wear resistance of the seal, etc., the seal must be exchanged for a new seal or else for a seal made of another material when the product to be tableted is changed.
- an improved filling shoe which makes it possible to achieve shorter downtimes when changing the seals.
- the seal in the mounted state is fastened to the bottom wall by means of magnetic force. If a change of seal is required in the filling shoe according to an aspect of the invention, it is possible, if appropriate even without any further aids, for the seal to be released by overcoming the magnetic holding force and then to be replaced with a new seal positioned at the same place.
- the seal could in principle be made of magnetized material, in particular of suitable material for high-energy magnets (supermagnets).
- the bottom wall could also be made of magnetized material, in particular of material for high-energy magnets (supermagnets) or comprise insert pieces or the like made of suitable magnetized material.
- the use of magnetic force, in particular the magnetic force of high-energy magnets, as a holding force for the seal has the particular advantage that it is possible to dispense with providing through holes or screw holes in the bottom wall of the filling shoe housing and in the seal.
- This not only eliminates weakened areas or minimized areas of, for example, the cross section of the body of the seal, at which areas the seal body may otherwise be subjected to wear or breakages, possibly even after a short time, but, given the fact that no cavities or holes have to be provided in the bottom wall and in the seal, also minimizes the number of cavities and the like which form undesired dead spaces in which constituents of the product to be compressed, in particular dust, powder bodies or the like, can accumulate and which require a complicated cleaning process during a change of product.
- the magnetic elements can be secured to the seal and/or to the bottom wall, with it being particularly advantageous if, to apply the magnetic force, the magnetic elements are secured in pairs both to the seal and to the bottom wall of the filling shoe housing.
- the use of pairs of magnetic elements makes it possible to achieve higher holding forces since the attraction force or the magnetic field of both magnetic elements can then be used to apply the magnetic holding force.
- the magnetic elements mounted, formed or secured on the seals may be elements of flat design, such as flat disks, flat cylinders or parallelepipeds, and/or be embodied as high-energy magnets.
- the magnetic elements which are used may particularly be high-energy magnets which have an energy product of at least 150 KJ/m 3 , in particular at least 200 KJ/m 3 , preferably at least approximately 250 KJ/m 3 .
- the corresponding high-energy magnets or supermagnets may particularly advantageously be made of hard ferrites, neodymium-iron-boron (NdFeB), samarium-cobalt (SmCO) or other suitable materials, for example of the rare earth metals.
- NdFeB neodymium-iron-boron
- SmCO samarium-cobalt
- the use of high-energy magnets made, for example, of NdFeB having an energy product of approximately 250 KJ/m 3 means that only a few magnets or pairs of magnets are sufficient to reliably apply the required holding forces.
- At least two magnetic elements, a magnetic element pair or a plurality of magnetic element pairs form a centering means for exactly positioning the seal relative to the discharge opening.
- at least two magnetic elements can be secured so as to project beyond the bottom wall of the filling shoe housing or beyond the upper side of the seal so that, by positively engaging in a depression in the counterpart, i.e. in the seal or in the bottom wall, the seal can be fixed in position.
- the countermagnet of the pair that may be present can then be arranged set back from the surface.
- the magnetic elements can be secured on the seal and/or in the bottom wall particularly by firmly adhesively bonding the magnets or pressing the magnets into corresponding receptacles.
- the magnetic elements or high-energy magnets can also be formed by means of curable and/or plastic-bonded, magnetizable materials or the like.
- the centering function could then be performed, if appropriate, also by centering pins or the like which are provided in addition to the magnets which define the holding force.
- the centering pins which may be additionally provided or the magnets which perform a centering function can at the same time also absorb some of the shear forces which inevitably occur in a rotating die plate during operation and which act on the seal in the peripheral direction or direction of rotation.
- the shear forces can be absorbed in particular through a positive connection between the magnet or centering pin and the bottom wall.
- some seals may feature a web which engages through the discharge opening and which at the same time particularly advantageously forms a removal aid for better gripping the seal to be released.
- a web which engages through the discharge opening and which at the same time particularly advantageously forms a removal aid for better gripping the seal to be released.
- the seal or the bottom wall may be provided with at least one wedge bevel for the application of a removal aid.
- a sealing element according to the invention for a filling shoe for rotary tablet presses improves the function of the filling shoe in that the seal is made of magnetized material, in particular of material for high-energy magnets, or in that magnetic elements, in particular magnetic elements made of material for high-energy magnets, are secured to the seal.
- the sealing elements or seals too, at least one magnetic element secured to the seal can advantageously be fastened in a projecting manner so that this magnetic element can be used at the same time to center or position the seal relative to the discharge opening.
- FIG. 1 is a perspective view of a portion of a rotor and of a filling shoe, partially cut away;
- FIG. 2 is a view of the underside of the filling shoe housing from FIG. 1 with a fastened seal
- FIG. 3 is a vertical section through the die plate and filling shoe which schematically shows the fastening of a seal using a plurality of magnetic elements.
- FIG. 1 shows a rotor of a rotary tablet press 1 , which is not shown in further detail.
- rotor 1 has an upper-punch guide ring 2 in which a plurality of upper punches 3 are guided in a vertically movable manner in suitable guides.
- the rotor also comprises a die plate 4 with a number of dies 5 corresponding to the number of punches, in which dies the punches press a product which is to be compressed, such as, in particular, powder, to form a tablet, and additionally a lower-punch guide ring 6 (only slightly indicated) in which, for each upper punch 3 , an associated lower punch 7 shown only in FIG. 3 is guided in a height-adjustable manner.
- a die plate 4 with a number of dies 5 corresponding to the number of punches, in which dies the punches press a product which is to be compressed, such as, in particular, powder, to form a tablet
- a lower-punch guide ring 6 (only slightly indicated) in which, for each upper punch 3 , an associated lower punch 7 shown only in FIG. 3 is guided in a height-adjustable manner.
- the number of punches 3 , 7 for each punch guide ring 2 , 6 and the number of dies 5 can vary between usually about 15 and up to 100, and corresponding rotary tablet presses can be used to produce tablets from a product to be compressed or else from a plurality of products to be compressed, such as, for example, multiphase pharmaceutical tablets or cleaning tablets.
- the rotor 1 In order to press tablets from a powder which is fed in, the rotor 1 is rotated in the direction of rotation R and the punches are moved up and down by means of suitable slotted guide tracks or curved guide tracks so that, depending on the position of the dies and punches 3 , 7 , the dies 5 can be filled with the product to be compressed, the tablet can be pressed or the pressed tablet can be ejected.
- a rotary tablet press comprises at least one filling shoe 10 which is fixedly assigned to the rotor 1 and to which the product to be compressed, such as, in particular, powder, is fed via a hopper (not shown) and suitable feed channels and feed tubes 11 leading to a filling shoe housing 12 .
- the filling shoe housing 12 here comprises a solid plate constituting a bottom wall 13 which is provided centrally with an approximately figure-eight-shaped distribution cutout 14 which opens into a continuous or, if appropriate multiply subdivided, discharge opening 15 on the underside 16 of the bottom wall 13 .
- impeller wheels 17 are driven via drive shafts 18 which lead, inside or outside the filling shoe housing 12 , to a motor drive so that the impeller wheel 17 can be rotated in the course of operation to move and distribute the product to be compressed.
- the filling shoe 10 can either be fixedly mounted inside the rotary tablet press or it can be articulated on a pivoting arm or the like in order, for the operation of the rotary tablet press, to pivot the filling shoe 10 into an operating position in such a way that the discharge openings 15 in a portion of the rotary tablet press lie directly above a plurality of dies 5 to be filled.
- the dies 5 in the die plate 4 are moved past the discharge openings 15 in the filling shoe 10 for a time span dependent on the speed of rotation of the rotor 1 and must be optimally and completely filled with the product to be compressed within this usually extremely short time span.
- the underside 16 of the bottom wall 13 of the filling shoe housing 12 is provided with a step 19 whose radius of curvature substantially corresponds to the outside diameter of the die plate 4 in order that the filling shoe 10 can be positioned with the smallest possible radial and axial distance from the die plate 4 .
- the die holes 5 A in the dies 5 should be filled as exactly as possible, and it should be ensured at the same time that, behind the filling shoe 10 in the direction of rotation R, as far as possible no product to be compressed projects beyond the upper edge of the dies 5 in the die plate 4 or is conveyed out of the discharge opening 15 .
- seal 20 which is open on one side here in the direction of rotation, said seal extending in the form of a circular arc around the discharge opening 15 by way of two segment legs 21 and having a transition curve 22 which connects the two segment legs 21 in such a way that, at the transition curve 22 at the latest, the product to be compressed is stripped off relative to the upper side of the die plate 4 by means of the transition curve 22 .
- the seal 20 is open between the two segment legs 21 .
- the seal 20 is releasably fastened to the underside 16 of the bottom wall 13 so that, depending on the product to be compressed, it has to be exchanged for a new seal 20 at longer or shorter intervals.
- the seal 20 needs to be exchanged regularly even when it is made of VA steel or bronze, for example, since at any rate when abrasive powder is used as the product to be compressed, the inner edge situated in the region of the transition curve 22 and facing the discharge opening 15 is subjected relatively quickly to wear which diminishes or cancels out the stripping function of the seal 20 .
- FIG. 3 The operating position of the, in this case rigid, sealing segment forming the seal 20 according to the invention relative to the die plate 4 is shown particularly clearly in FIG. 3 , to which reference is now made.
- a relatively large gap which is substantially completely bridged by means of the seal 20 fastened to the underside 16 .
- there nevertheless usually remains a gap clearance in the region of about 1/10 mm between the lower surface of the seal 20 and the facing surface of the die plate 4 .
- the seal 20 in the filling shoe 10 according to the invention is fastened to the underside 16 of the bottom wall 13 by means of magnetic force alone.
- the magnetic holding force between the seal 20 and the bottom wall 13 is applied using respective pairs of magnetic elements 26 and 28 , with the magnetic elements 26 being arranged and secured on the upper side of the sealing segment 20 and the magnetic elements 28 being arranged and secured on the underside 16 of the bottom wall 13 .
- the magnetic elements 26 , 28 can be secured in particular by adhesively bonding them in place or pressing them into place, and the magnetic elements 26 , 28 are preferably flat and at the same time relatively wide high-energy magnets, such as, for example, so-called supermagnets made of hard ferrite or neodymium-iron-boron (NdFeB).
- one or preferably more pairs of magnetic elements can at the same time be used to provide centering means, as is indicated for the magnetic elements 27 and 29 in the left half of FIG. 3 .
- the centering takes place in such a way that the magnetic element 27 secured to the upper side of the seal 20 projects beyond the upper side and, at the same time, the magnetic element 29 secured in the bottom wall 13 is set back with respect to the underside 16 , thereby allowing the magnetic element 27 to fit positively into a recess 25 on the underside 16 and in so doing to center the seal 20 .
- a plurality of magnetic element pairs simultaneously form a centering or positioning means.
- the centering or positioning means could also be designed or arranged in such a way that they can also be used to absorb shear forces in the direction of rotation of the rotor.
- the fastening of seals using magnetic force can be substantially achieved with any design of seal or sealing segments, and the seals could also, for example, form closed rings, have a multi-part design or be provided in other formats.
- the transition curve in particular can be designed as a partial segment which can be exchanged separately from other partial segments of the seal, since the greatest wear normally occurs on the transition curve.
- the seals are preferably made of copper, stainless steel or bronze; however, it would also be possible to secure corresponding high-energy magnets to seals made of plastic or other materials.
- the entire sealing segment from a magnetized material, in particular from a material for high-energy magnets, with the result that the sealing segment 20 is therefore fastened self-adhesively to the underside of the bottom wall 13 .
- the magnetic element or high-energy magnets can also be pressed directly into recesses or the like in the sealing segment and/or the bottom wall of the filling shoe housing and/or also be made, for example, of plastic-bonded magnetic materials based on NdFeB or based on hard ferrite, of sintered hard ferrites, or other sintered or plastic-bonded materials, rare earth materials or the like having high-energy magnetic properties.
- the die plate may have a different construction and be composed, for example, of subsections having integral die holes or have cutouts for insert pieces which comprise a plurality of die holes.
